Fur color in rabbits is determined by a single gene locus for which there are four alleles. four phenotypes are possible: black, chinchilla (gray color caused by hite hairs with black tips), himalayan (white with black patches on extremities), and white. the black allele (c ) is dominant over other alleles, the chinchilla allele (c^ch) is dominant over himalayan (c^h) and the white allele (c ) is recessive to all others. a) a black rabbit is crossed with a himalayan, and the f1 consists of a ratio of 2 black to 2 chinchilla. can you determine the genotypes of the parents

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
